Well I finally decided to trade up from my F150 to the power of a 6.7. Honestly, I got bored with my F150 and wanted something bigger and better. However, I'm new to the diesel side of engines and from what I've seen, there isn't much out yet for the 2015's. I'm looking for input on the best riding 6"-8" lift for my new project. Don't want to lose to much of the factory ride. I have a BDS lift on my F150. Does the BDS ride as good on the heavier F250? Performance exhaust system? What systems have been field tested and prove from you guys? And of course, with the exhaust comes a new intake system. Which performs better from the big names such as S&B, K&N, etc? Thanks for the input guys.
